Battery powered lawn mowers have seen significant improvements in grass cutting efficiency and battery capacity. With dozens and dozens of models to choose from, Consumer Reports has published test results for 50 different mowers.
How did Consumer Reports test battery lawn mowers?
Consumer Reports tested the mowers under “constant” and “ideal” conditions, meaning a flat, unobstructed yard. For consumers, the choice of battery-powered mower will depend on their physical stamina. To help, Consumer Reports has divided its test between pushed and self-propelled examples.
The best battery-powered self-propelled lawn mowers tested by Consumer Reports
Battery-powered self-propelled mowers typically give 10 minutes less mowing time than push powers due to the energy expenditure for movement. Still, they cut slightly faster, covering more area than a push mower at the same time, about 2,500 square feet more.
Greenworks MO80L421: $750
Although it is expensive, you will get what you pay for. consumer reports ranks it top for mulching ability and dumping, following thick grass under the 21-inch deck, also offering excellent handling and lower noise levels than others. The Greenworks has a runtime of nearly 75 minutes when you swap out the included extra battery. Plus, its four-year mower and battery warranty is favorable in a market that typically only provides three.
Ryobi RY401210US: $799
Consumer Reports rated the Ryobi near-perfect in every category except bagging, for which it still received high marks. With 75 minutes of trimming time with the extra battery, this 21-inch trimmer can also be easily stored upright; it also comes with a generous five-year warranty.
Me LM2156SP-2: $1000
Most may balk at the price; however, the Ego is one of the most capable and versatile in the segment. With a 21-inch deck and two batteries running back-to-back, it can tackle two hours of mowing time and excels in rough terrain. Mower batteries can also be used in other Ego branded power tools, providing potential cost savings. A five-year warranty on mowers and batteries means future mowing problems can be alleviated.
Me LM2142SP: $799 to $849
If $1,000 seems like too much, you can opt for its smaller sibling. Users can still enjoy the ease of handling and rugged reliability of the more expensive model, sacrificing only a tiny amount of mulching and charging time superiority. The manufacturer’s warranty is three years instead of five for the battery, but you can still use them in all your Ego power tools.
DeWalt DCMWSP255U2: $650
With a 21½-inch-wide deck, the DeWalt puts more blade coverage on the grass, reducing the time it takes to put lines in your yard. Either way, its 70-minute runtime on two 20-volt batteries will ensure excellent shredding and the ability to cut evenly. The DeWalt has the potential downsides of average bagging capacity, a standard three-year warranty, and a battery charge time of over nine hours.
The best battery-powered lawn mowers tested by Consumer Reports
If your mowing conditions are barrier-free and relatively flat, you can opt for a battery-powered mower. Although cutting takes longer, the simplicity of a mower can lead to better reliability.
Ryobi RY401220P: $734.00
Since the Ryobi comes with two batteries – one you can swap the other for mid-mowing – you can cut for an hour and a half before charging, more than any walk-behind mower tested by Consumer Reports. The 21-inch mower offers excellent performance in mulching, unloading and consistency of cut; it comes with a five-year warranty on the mower and a three-year warranty on the battery from the factory.
DeWalt DCMWP233U2: $449-$549
This moderately priced 21½-inch mower has an 80-minute runtime from two batteries used simultaneously, helping you power through the grass. While it offers less-than-stellar bagging capabilities and a slow seven-hour charge time, it’s a powerful mulcher, discharges easily, and is one of the quietest mowers around. Plus, it comes with a respectable three-year warranty on the battery and a three-year warranty on the trimmer.
Electrical equipment DR CE75021XEN0: $650
DR Power Equipment’s 21-inch lawn mower can cover a third of an acre in 70 minutes on a single battery. If that’s not enough, the battery can be charged in just over an hour. However, its guarantees leave something to be desired: one year for the battery and two for the machine itself.
How to make your battery-powered mower run longer
Regardless of the type of battery mower, treating it properly can help its longevity. Here’s how to get the most out of your mower:
Don’t let your garden get out of hand. Mow on a regular schedule, so you’re only cutting a few inches from the top rather than baling hay and draining your battery.
Sharpen blades once a month during mowing season. Dull blades require more energy to cut.
Charge the batteries between mowing and do not store them in the mower when not in use.
